Prying Tile From Finished Mosaic

How To Pry Up Tiles To Modify A Mosaic

I have often used a small screwdriver to pry up tiles when I wanted to change some detail in a mosaic, but in all of those cases, the mosaic had a grout gap, and it was possible to knock an individual tile out or shatter it without damaging its neighbors, at least most of the time.

But what if you can’t afford to damage surrounding tiles or you have a mosaic with no grout gap? Is it even possible to get tiles up? The answer is yes, and the method involves a wet cotton swab, a dental pick, and a sharpened chopstick.

Mosaic Picture Frame Iso View

Mosaic Picture Frame

Angela made a mosaic picture frame using our irregular glazed ceramic tile and left the sides of the frame uncovered. She also nested the angular shapes to created an abstract pattern without cutting any of the tiles to make them fit.

The unfinished side edges of Angela’s mosaic look particularly neat because the sides of the ceramic tile is straight and not beveled like the sides of vitreous glass mosaic tile, which could still be used if you didn’t mind an edge that was a little rougher. Continue reading

Mosaic Christmas Ornaments by Phyllis Kempter

How To Efficiently Make Mosaic Christmas Ornaments

Artist Phyllis Kempter emailed me some photos of the ornaments she made using our kits for 3-inch spherical mosaic Christmas ornaments and our 12mm recycled glass tile (plus a few other sizes of tile), and her ornaments caught my eye for two reasons:

First, she used green in the patterns for her ornaments, which is good to do if you think the ornament might by hung on something other than a Christmas tree, at least some of the time. Green might not help the ornament stand out on the tree as well as red would, but it goes a long way toward suggesting Christmas when the ornament is not on a tree, especially when used with red.

Second, one of her photos was of her well-organized work space, and it illustrates several methods and tips for making the tiling process easier and faster. Continue reading

Mosaic Mirror Oxidation Detail

Mirror Mosaic Warning

Silver-backed mirror must be glued down using a special mirror adhesive; otherwise the reflective silver will oxidize and turn black. Mirror tile is a different situation.

Mirror Vs Mirror Tile

Note that this warning is about pieces of broken mirror being used as tile. Mirror tiles such as the colored glass mirror tile we sell have a special epoxy coating over the silver to protect it from adhesives. In that case, you can use Weldbond and do not have to worry. Continue reading

Staining Grout with Acrylic Paint

Staining Grout With Acrylic Paint

Mosaicists sometimes mix in artist acrylic paint to create custom colors from white grout, but you can also use acrylic paint to “stain” grout after it has hardened (for dry indoor mosaics).

Like the process of staining wood, “staining” grout with paint is a process of wiping on and wiping off. The paint sticks to the rough grout but wipes off the glass tile. Continue reading

Common Ground Public Art Mosaic Tables

Materials and Methods for Outdoor Mosaic Tables

Artist Risa Puno recently completed her interactive mosaic sculpture Common Ground for Rufus King Park in Jamaica Queens, NYC, and the project is a great example for discussing materials and methods for mosaic table tops.

No Plywood Backers Outdoors

Plywood is never an acceptable backer for outdoor mosaic table tops.

Humidity in outdoor air can cause plywood to swell, contract, and warp, and even if the displacement is too small to be noticed, it can still cause grout to crack and tiles to pop off. Once grout has hairline cracks, moisture can penetrate underneath, and then there isn’t any hope for the mosaic lasting after that happens.

If you have a wooden table that you want to mosaic for outdoors, then attach a piece of 1/4-inch concrete backer board over the top of the wood and mosaic on that. 

Seal your finished outdoor mosaic with a tile and grout sealer and reseal it each fall. Silicone-based gout sealers are wipe-on-wipe-off and easy to apply. Most of the work is buffing off the excess so that the surfaces are slippery. Continue reading

Why Did My Tiles Come Loose From Thinset?

Recently, artist Jackye Mills emailed me about a problem she was having with her first mosaic project, and it really caused me a lot of angst because the artwork was a strong design that was otherwise well executed. I hated the thought that a first-time mosaicist could do such a good job on something so ambitious only to lose the project due to a technical issue. Continue reading

Cutting Vitreous Glass Mosaic Tile diagonally to make triangles.

How to Cut Diagonal Triangles from Vitreous Glass Tile

Many people report having trouble cutting vitreous glass mosaic tile reliably because of the embossed patterns on the back sides, which can interfere with the blades of the mosaic glass cutter, but if you take simple steps to minimize interference and rotation, it can be done.

What I mean by interference is when the blade slips down into a valley between two ridges instead of staying positioned in the desired line of the cut. Continue reading

Lighthouse Mosaic By Natalija Moss

Making Pictures With Colored Mirror Tile

Natalija improvised this picture of a lighthouse using the Colored Mirror Tiles to show that they can be used to render an image. We added these tiles last year, but I haven’t had time to use them in anything.

In Praise of Colored Mirror Tiles

I can say that the Colored Mirror Tile ranks the highest of all our product lines in terms of being “pretty shiny things” in a rainbow of colors. (Sure the 24kt Gold Mosaic Glass is dazzling, but that is only one color, and things like beads and gemstones are more accents than they are materials for rendering.) Continue reading

Online Source of New and Used Mannequins

People ask me about mosaic mannequins from time to time, and usually it is which adhesive to use for attaching tile to an old used mannequin they bought at a thift store. I also get questions about where to find a mannequin to use as a mosaic base, and I could only suggest eBay, garage sales, thrift stores and places the asker had already tried. Thankfully Judi Townsend at Mannequin Madness has let me know that they sell new and used mannequins online.

What Adhesive For A Mannequin?
